Having never read a spec sheet before is this saying that to get optimal mAh you need to discharge at about 260 mA?
Would discharging at higher currents dramatically decrease the capacity?
I ask because I have a ton of these testing rather low but I'm discharging at around 500Ma.

Having cataloged so many cells, it seems when these companies test cells they test at 0.2C to get the "standard discharge rate" and capacity. I don't think testing at 500mA would give a substantial difference, if there even is a difference at all. If you pull up the spec sheet, there is a graph showing capacity over various discharge rates.
